在用到checkbox的时候发现php只能取一个值，查了相关资料，原因如下：
Php代码
<input type="checkbox" name="weeks[]" id="weeks" value=1> <input type="checkbox" name="weeks[]" id="weeks" value=2> <input type="checkbox" name="weeks[]" id="weeks" value=3>
weeks后的中括号不可漏，否则用PHP获取的时候只能取到最后一个值。之后PHP就很好处理了，如下:
Php代码
方法一： $weeks = $_POST['weeks']; for($i=0;$i<count($weeks);$i++) echo $weeks[$i]."<br>"; 方法二： $array = $this->request->getParameter("weeks[]"); $str =implode(',',$array); echo $str;
